| Abstract: | A kinematic solver for planar linkage applied in virtual prototyping simulation was developed,which was based on automatic identification and transfer of assure groups and single-bar.As the solver directed to one motion-independence chain,when a virtual prototyping was composed of several motion-independence chains,a problem occurred that how many times the solver should be used.This paper,through an introduction to new concept of motion-independence chain,presented the principles of its recognition,relationship between basic loop,and its realization steps,associated with incidence matrix and basic loop matrix.Finally,an internal-combustion engine and a press,as examples of virtual prototyping,were given to show the correctness of the method. |
| Keywords: | virtual prototyping motion-independence chain kinematic analysis simulation |
